PC speaker question

I have been looking for a set of pc speakers that meet my two criteria to no avail. I want a set of pc speakers that have an optical input and are magnetically shielded....Is this out there?? the only sound system that i can find with optical in is the logitech z5500 but it has that huge frickin sub that is not magnetically shielded and can't be put near electronics. My room layout and space issues mean that i will need to be placing everything in close proximity to my PC. Is there a set out there that has speakers and sub magnetically shielded with optical in???

Price is not a factor. thanks in advance....by the way are the satellites of the z5500 magneticall shielded?

You would think that being designed for PC use that they could have shielded that sub...makes no sense to me

Input greatly appreciated.
